Electrocoagulation for the removal of phenol and aldehyde contaminants from resin effluent

This paper is a report on a study which aimed to investigate the effect of different current density, pH, temperature, and cathode–anode combination on the removal of phenol and aldehyde in two samples of actual resin effluent through the process of electrocoagulation using solar energy. Current density 60 A/m2 and pH 6 proved to be the best levels for both contaminants. As for the effect of temperature, although the highest degree of phenol and aldehyde removal was achieved at 15 °C, 25 °C was taken to be the optimum temperature for economic reasons. The Fe-Fe combination of electrodes was found to be the best as it led to nearly 93% of phenol removal and approximately 95% of aldehyde removal. Also, the effect of electrode combination on energy consumption was studied. It was observed that the Fe-Fe combination consumed the least amount of energy (0.7–4.3 kWh/m3 of wastewater in the case of phenol and 0.8–4 kWh/m3 of wastewater in the case aldehyde). Moreover, the Fe-Fe combination brought about the best results in terms of chemical oxygen demand removal: 93% in both cases. Finally, an economic analysis was performed for the electrocoagulation process.

In this paper, an experimental study upon alkalinity and hydrodynamic behavior in an anaerobic up-flow fixed bed reactor for the treatment of tequila vinasses is presented. Measurements of volatile fatty acids, pH, alkalinity and bicarbonate were obtained at three sampling points in the reactor in the axial axis. Then, the spatial distribution of alkalinity is studied and discussed. Moreover, for further control process purposes, a hydrodynamic model based on the use of two interconnected two-steps reduced AM2...

Of the most commonly used calcium carbonate (CaCO3) saturation indices, the Calcium Carbonate Precipitation Potential (CCPP) most accurately describes CaCO3 precipitation and dissolution. This paper illustrates how to write an OpenModelica programme that calculates the CCPP and other key water parameters starting from total alkalinity and CO2-acidity. It describes the calculation steps of all components of the developed OpenModelica package and explains how the components work together. Underlying chemical...

Summary
Multi-tasking and time allocations are key components to running an efficient laboratory and decreasing the cost per analysis for pH, conductivity, alkalinity, chloride, fluoride and ammonia. The cost of analysis has risen over the years while revenue from these parameters has remained the same. Much of the high cost is due to the use of multiple instruments, multiple trained technicians and...

The cost of analysis has risen over the years while revenue from these parameters has remained the same. Much of the high cost is due to the use of multiple instruments, multiple trained technicians and outmoded automation available. By the development of a single automated system, with computer control, capable...
